Description

IC card

The present invention relates to an IC card. In particular, it relates to the structure of an IC card such as CFast which is connected to a slot provided in a computer.

For example, in order to expand the function of a personal computer (hereinafter referred to as a PC), an expansion card to which a connector is attached to a printed circuit board mounted on a microprocessor is connected to an expansion slot of the PC. The CFast card is a type of expansion card that is standardized for PCs and is connected to a PC for high-speed communication.

The CFast card is a type of an IC card in which a printed circuit board on which a microprocessor is loaded is housed in a frame of a rigid body. Thus, a CFast card can be classified as a microprocessor card that is different from a memory card that is sealed to a plastic package. In addition, in recent years, CFast cards with keyboards have appeared, and CFast cards can also be classified as multi-function cards.

Such an IC card may cause damage to electronic components mounted on a printed circuit board due to static electricity from the outside. Therefore, it is necessary to carry out countermeasures against static electricity. Therefore, it is desirable to have an IC card that implements countermeasures against static electricity having high reliability.

For example, an IC card according to Japanese Patent No. 3167416 (hereinafter referred to as Patent Document 1) includes a printed circuit board, a connector, and two planar conductive plates. The printed substrate is loaded with electronic components. The connector is arranged with a predetermined number of connector pins in the connector frame and mounted on the printed substrate. Moreover, the ground pins in the connector pins of the connector are connected to the ground pattern of the printed circuit board. A pair of conductive plates are abutted on the upper and lower sides of the connector frame.

Next, the IC card of Patent Document 1 forms a penetrating portion penetrating the conductive plate side on the upper and lower sides of the connector frame corresponding to the ground pin. again A protruding piece is provided on the upper and lower sides of the grounding pin. Thereafter, each of the protruding pieces is elastically engaged with each of the conductive plates that are pressed and deformed in the penetrating portion by sandwiching the upper and lower surfaces of the connector frame with the conductive plates.

The connector frame of the IC card of Patent Document 1 functions as a stopper member for a component or a conductive plate on the manufacturing line. Therefore, even if the conductive plate or other member presses the protruding portion of the grounding pin, when the conductive plate or other members finally abut against the outer surface of the connector frame, the pressing deformation of the protruding portion of the grounding pin can be prevented. . Therefore, the protruding portion of the grounding pin can be prevented from being excessively deformed, and the contact between the grounding pin and the conductive plate can be satisfactorily maintained by any IC card to improve the reliability of the countermeasure against static electricity.

According to the IC card of Patent Document 1, the grounding pin has a box-shaped lead-in "female contact" which is easily inserted into the "positive contact". Moreover, the ground pin is provided with a protruding piece.

The "male contact" as described above is formed by punching a metal plate which is developed into a predetermined shape into a box shape. Further, if the "yang contact" is manufactured in a chain state and is made "chain-like contact", it can be mass-produced, and automatic assembly becomes easy.

However, since the interlocking contact is wound around the reel and is manufactured, when the protruding piece is provided like the grounding pin disclosed in Patent Document 1, the protruding piece may be deformed during the state of being wound around the reel or during the transfer. That is, when the protruding piece of the grounding pin is deformed, it is difficult to accurately assemble the protruding piece of the grounding pin to the connector frame, and there is a fear that the countermeasure against static electricity of the IC card cannot be achieved.
